Versão 0.24.1
Lançado em 3 de jul de 2026 - 495,58 KBFunciona em firefox 115.0 em diante, android 120.0 em diante- NSCL Update related to a bug in script injection to Firefox where 0.24 hid MutationObserver.prototype from page scripts (that might break pages requiring the prototype and/or reveal that JShelter or similar webextension is installed). See https://github.com/hackademix/noscript/issues/572 and https://github.com/hackademix/nscl/commit/e0849aa9df8d47d36b9beb3b21f4c92a5f06792a for the context.

Versão 0.24
Lançado em 1 de jul de 2026 - 472,65 KBFunciona em firefox 115.0 em diante, android 120.0 em diante- NSCL update:
- Improved corner-cases in script injection in both Firefox and Chromium-based
browsers. - Avoid issues related to MutationObservers, see https://lists.nongnu.org/archive/html/js-shield/2026-06/msg00003.html and the related thread
- Improved corner-cases in script injection in both Firefox and Chromium-based
- Set Workers to Strict by default, see https://codeberg.org/JShelter/webextension/issues/156 and https://codeberg.org/JShelter/webextension/issues/177 for the reasoning.
- Reconsider the approach to modify Web Audio that was reimplemented in 0.22. The farbling (recommended level) essentially returns to the original concept but the memory footprint of JShelter improves as it uses WeakMaps to store farbled Web Audio buffers for the duration of their existance. The approach to farble floats in the Web Audio API changed slightly to avoid revealing the lower bound of the readings and to farble 0s. This approach should brake less page scripts. The white noise has very limited amplitudes close to a silence.
- Allow users to configure JShelter not to interfer with pages where their disable both JSS and FPD.
- Do not show NSCL log messages as they may confuse users

- NSCL update:
Versão 0.23.1

Versão 0.23
Lançado em 1 de jun de 2026 - 471,18 KBFunciona em firefox 115.0 em diante, android 120.0 em diante- Quietly discard possible exceptions that were thrown in 0.22.1, which fixes the interaction with AdGuard.
- Update NSCL to 13.6.20 (latest version). It should provide several changes to JShelter, including avoiding contentScript.register() (see issue #175).
- Refactor mechanism to determine when to propagate detected API calls to background introduced in 0.22.1. The mechanism should be essentially the same but behave better on some pages.

Versão 0.18.1
Lançado em 28 de jun de 2024 - 441,59 KBFunciona em firefox 79.0 em diante, android 120.0 em dianteFix the scope where updateCount used by FPD is created (Pagure issue 141. Although the function was not visible to page scripts, page script could have define their own function with several consequences as JShelter would call the page script function:
FPD would not learn about the calls and consequently would not detect fingeprinting attempts by the page,
pop up would not show calls to the wrapped APIs,
the page would be able to detect that JShelter is being installed,
if the page would not expect that someone is calling its function it can have any undesired consequences.
The bug was present in JShelter since the introduction of FPD in 0.6 and all versions up to 0.18 are affected.Código fonte publicado sob Somente GNU General Public License v3.0

Versão 0.17
Lançado em 3 de nov de 2023 - 447,3 KBFunciona em firefox 78.0a1 em diante, android 120.0 em diante* Added support for built-in tweaks for specific domains. The goal is to list several domains that
break unnecessarily. Typically, an addition to the list should be well explained and must not
lower protection. A nice candidate is WebWorker and the protection of Strict (break) and Remove.
* Updated translations
* Improved FPD report based on user feedback:
* Do not refresh report automatically when tracking callers but introduce an update button so that
users refresh when convenient (prevent glitches in the interfaces)
* Add buttons to hide/show details and fold/unfold groups
* Do not show traces in bold to better differentiate between API names and traces.
* Add possibility to forget current traces. Useful when there is a fingerprinting script that activates after some action. The button allows the user to hide the traces triggered in the past and later load only new traces.
* Add support for signing for Android on AMO: https://blog.mozilla.org/addons/2023/10/05/changes-to-android-extension-signing/, so we needed to increase minimal supported versionCódigo fonte publicado sob Somente GNU General Public License v3.0

Lançado em 27 de set de 2023 - 427,93 KBFunciona em firefox 68.0 em diante* Remove Workers in Recommended JSS level to make JShelter compatible with some pages. This change might be reverted when [Pagure issue 80](https://pagure.io/JShelter/webextension/issue/80#comment-852202) is solved.
* FPD: Add possibility to learn the calling stack of functions that lead to the tracked APIs ([Pagure issue 52](https://pagure.io/JShelter/webextension/issue/52)). This information can be used to create block list or to study the calling code and its effects.
* FPD: Fix browser overloading by FPD messages by HTMLElement.prototype.offsetHeight and offsetWidth wrappers that might have crashed browsers.
* FPD: code cleanupCódigo fonte publicado sob Somente GNU General Public License v3.0
Versão 0.15.2

The fix affects all Chromium-based browsers and Firefox installs with the protection active (by default it is off in Firefox as Firefox contains the protection since Firefox 88). This fixes, for example, reCaptcha.
